| 摘 要： | 吸附作用是疏水性有机物在土壤和沉积物环境中的重要迁移转化行为之一。多环芳烃是环境中一种重要的疏水性有机污染物。文章着重阐述了多环芳烃类有机物在土壤和沉积物中有机质和粘土矿物吸附机理，指出土壤、沉积物有机质的结构异质性是导致非线形吸附的重要原因；分析了影响多环芳烃吸附过程的诸多因素，并提出该研究领域存在的问题以及今后发展的方向。

| Abstract: | Sorption is one of the most important behaviors of transportation and transformation of hydrophobic organic contaminants (HOCs) in soils and sediments environment. Polycyclic aromatic hydrocarbons (PAHs) are important hydrophobic organic contami-nants (HOCs). This thesis expatiates on the progress in the researches on the sorption mechanism of polycyclic aromatic hydrocar-bons (PAHs) by soils and sediments, and discusses impacts of structure heterogeneity of soil and sediment organic matter on nonlin-ear adsorption of PAHs. This review puts forward some problems in the field and the development direction in the future. |
